Diphyllobothriasis in humans is caused by a
parasite called Diphyllobothrium latum. This parasite belongs to
the phylum Platyhelminthes and the class Cestodes. Cestodes are more
commonly known as tapeworms due to their flat, ribbon-like body. Diphyllobothrium
is the genus to which numerous species belong. Latum is the name of the species
that primarily infects humans. Although, several other Diphyllobothrium
species have been reported to infect humans, but less frequently; they include D.
pacificum, D. cordatum, D. ursi, D. dendriticum, D. lanceolatum, D. dalliae, and
D. yonagoensis. D. latum is believed to be the largest human tapeworm,
often growing to lengths between 1 and 2 meters (3-7 feet) and potentially
capable of attaining 10 meters (32 feet). Other
synonyms for this parasitic disease are Dibothriocephalus anemia, fish tapeworm
infection, and broad fish tapeworm infection.

Chances are that if you have ever eaten any
Sushi, ceviche or uncooked fish you have been at risk for being infected by D.latum!
(although not at sufficiently high risks...) So read on!
